Touch Screen Camera Control for Video Conferencing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional video conferencing systems lack intuitive and precise control methods for cameras, often relying on complex control panels that do not display camera outputs, leading to difficulties in adjusting camera views and following speaker movements effectively.
Innovation Solution
Implementing a gesture-based control system that allows users to interact with a touch screen to control cameras through touch inputs, displaying both camera views and wide-angle views to facilitate intuitive control, including zooming, panning, and focusing on specific areas or objects.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If conventional control panels are used to control cameras, then the system structure is simple, but the ease of operation deteriorates because users cannot intuitively control camera views and follow speaker movements
Solution Approach 1:
The patent creates a visual copy of the camera view on the touch screen, allowing users to interact with the camera output image itself. Touch inputs on the displayed camera view directly translate to camera control commands, eliminating the need for separate control panels and making the system intuitive to operate.
Solution Approach 2:
The touch screen serves as an intermediary between the user and the camera system. It displays the camera output and translates touch gestures into camera control commands, providing a natural and intuitive interface that improves ease of operation without significantly increasing overall system complexity.
2Ease of operation
If complex control panels are implemented to enable precise camera control, then the ease of operation improves, but the device complexity worsens
Solution Approach 1:
Instead of using complex control panels with multiple buttons and switches, the patent displays a copy of the camera view on the touch screen. Users can directly touch and drag the displayed image to pan the camera, or pinch to zoom, providing precise control through intuitive gestures rather than complex physical controls.
3Ease of operation
If touch screen interface is implemented for gesture-based control, then the ease of operation improves, but the device complexity worsens due to additional screen capabilities
Solution Approach 1:
The touch screen serves multiple functions: it displays the camera output view, accepts gesture inputs for pan and zoom control, and provides visual feedback during camera operations. By making the screen multi-functional, the patent improves ease of operation without requiring separate dedicated control devices, effectively managing the complexity trade-off.

AI summary
Systems, methods, and non-transitory computer readable media are configured to obtain video data from a camera used in a video conferencing system. A user interface displaying the video data can be provided on a screen, wherein the screen is capable of receiving touch input. A first touch input associated with a function of the camera can be obtained. The first touch input can be received from the screen. An instruction for executing the function can be sent to the camera. The user interface can be updated in response to the execution of the function of the camera.
